SPECIFICATION forming part of Letters Patent No. 777,269, dated Decemberl3, 1904.

Application filed October 8, 1903.

To all whom it may concern.-

Be it known that I, FRANK. WATKINS,& citiaen of the United States,residing in Burton, county of King, and State of Washington, haveinvented certain new and useful Improvements in Sharpening Attachmentsfor (jutting-Tools, of which the following is a specificainn.

My invention relates to the construction of" the handles ofcutting-tools so that a whetstone may be detachably secured thereto; andthe objects of my invention are, first, to provide a tool-handle whichwill always have the means for sharpening the tool at hand, and, second,which will so protect the Whetstone at all times that there will bepractically no danger ofits becoming cracked or broken. I attain theseobjects by the device illustrated in the accompanying drawings, inwhich-- Figure 1 is a top, view of a pocket-knife having my Whetstonesecured in place in the handle.- Fig. 2 is a-section of same. Fig. 3 isa side view of the Whetstone detached from the knife-handle. Fig. l isapartialtop view thereof, and Fig. 5 is aside view of the knifehandlewith the Whetstone removed therefrom,

Similar letters of reference refer to similar parts throughout theseveral views.

I have illustrated my invention as applied to a pocket-knife and willdescribe it in detail, as shown on the drawings; but I do not wish it tobe understood that I confine its use to pocket-knives, but, on thecontrary, claim that it can with but very slight modifications be usedin connection with any cutting-tool which has aspace large enough toreceive a whetstone adapted to sharpen it.

The knife illustrated is a singlebladed pocket-knife having a blade Apivoted in the usual manner at one end at B to the head 0 of the handle.This handle is usually constructed with its sides of bone; but in myinvention only one side D is of the usual con struction, the other sidebeing formed of a metal piece E, engaging the head C and the end F andbent so as to conform to theoutline of the side of the knife and havingthe sets N6. 176,279. (No model.)

Whetstone G secured to its inner side, so that it lies between the pieceE and the side H of the blade-recess. The parts C and F of the handleareprovided with grooves'l, which I the sides of the grooves I.

The Whetstone G is secured by any suitable means to the piece E -as, forinstance, it-

might be cemented thereto, or the sides of the piece E might be bentaround the stone to secure it in place. The Whetstone is-protected fromdamage at all times by the casing E, in which it is secured. r

My device is used in the following manner: When the blade is dull, thepiece E, with the whetstoneG secured to it, is slid along the side Huntil the ends J are disengaged from the grooves I, and it is then heldso that the blade can be sharpened. l/Vhsn this has been done,

the Whetstone G is turned so that its face will come against the sideII, and the ends J of the piece E are made to engage the grooves I andthen it is pushed to its normal position.

Wliat I claim, and desire'to secure by Letters Patent, is-

1. In combination, a cutting-tool handle having a recessed surface onone side thereof with grooves in the ends of the recess, a removableprotecting'= frame engaging said grooves and bent to form a spacebetween it and said recessed surface, and a sharpew ing medium securedto said protectingdrame within said bends thereof whereby said space isfilled substantially as shown and described.

2. In combination, a cuttingtool handle having a recessed surface on oneside thereof with grooves in each end of the recess, said groovesbeingwedge-shaped, a sliding protecting frame having wedge shaped endsadapted to engage and slide in'said grooves and being bent to form aspace between it and said recessed surface, and a sharpening mediamsecured to said protecting-frame within said bends thereof in suchmanner that said space is substantially filled.

3. In combination, a cutting-moi handle having a recessed surface on oneside thereof,

a sharpening medium, and a protective cas-.

ing eerrying the same and adapted to secure the sharpener Within therecesses set forth.
